The hot forging mold device for low-pressure casting includes an upper and lower mold forming a cavity, a riser cavity that supplies molten metal, and a press device positioned above the riser cavity to apply pressure. A sensor and controller can adjust pressure based on the molten metal's temperature or fill level. Cooling fluid circulates through a cylinder base plate, and an insulating plate reduces heat transfer. An ejection device, moved by an actuator, removes the solidified cast product. Guide blocks help align components, and a leakage preventing plate with a seal helps avoid fluid intrusion. The overall design ensures efficient feeding of molten metal, controlled forging pressure, and reliable ejection, improving casting quality and reducing defects.
